GENMAX for the Win!

I recently purchased from Sam’s Club the Genmax GM5500XiD inverter generator, and I’m thoroughly impressed with its performance! Setup was quick and easy, taking just minutes! I used it to power my electric pressure washer, and it delivered flawless and reliable power. I opted for LP gas as the fuel source, and the dual-fuel capability worked seamlessly, offering flexibility and convenience. Its quiet operation makes it ideal for any setting, while the digital control center provides real-time updates on voltage, fuel level, and run hours. The sturdy wheeled frame allows for easy maneuverability. The generator’s outlets provide versatility for connecting various devices and appliances, including RV systems and heavy-duty equipment. It also has a couple of USB ports! I also reached out to their support as I had a couple of questions regarding specs and maintenance in which they were very professional and knowledgeable. Highly recommend this generator for its power, safety features, portability and support!

Generator Looks, Feels, and Performs Soild!

I'm not a big review guy but this unit performed so well that I felt compelled to share. First of all, right off the bat, the packaging is Solid. The unit came strapped, stapled, taped, bagged, and included internal v-board on all four sides. Thats how you protect your investment. The unit looks and feels Solid! Another A in that category too. I used the generator to power up my Skilsaw to cut some baseboards for 3 bathrooms at one of my rental properties. I also used it to power up my Dewalt jackhammer because I had to break up some uneven concrete. Sorry for the details. Anyway, the point I am trying to make is that this unit is well built, and I recommend it. Period. You will not be disappointed. Great work Genmax. Keep up the Good Work!

Couldn’t be happier

This is a seriously impressive generator. Packs huge power in a small package and it’s a lot quieter than my last generator. Took it camping and I powered my buddy’s airstream including AC no problem. Really nice to be able to use propane or gasoline. Have also used it for work on a construction site and it hasn’t missed a beat. Assembly is easy and quick and everything needed came in the box including oil. I called Genmax to ask a few questions and was very pleasantly surprised with how knowledgeable and helpful they were. Would recommend to anyone looking for generator. I’m going to buy another one for a home backup since you can link them together.

Good So Far

Only ran 5 hours so far. Able to power my camper including coleman mach 48200 AC, at 4700 ft elevation, on either propane or gas. Should be good for my needs. Starts up easily. Nice that it's light enough to lift into my truck by myself.

Great Generator Upgrade

My last generator crapped out after years of use and I was looking for a new one to replace it. After considering several generators, I decided to purchase the Genmax generator as it checked all the boxes and was affordable. When it arrived I was happy to see that they included everything including tools, oil, and even an LP gas hose. I was surprised by how compact, lightweight, and quiet this generator was. This thing has everything you could want - multiple outlets, covers for the switches and outlets to keep dirt and moisture out, and even a USB port. I am happy with the large 2.2 gal gas tank and the icing on the cake is the ability to run on propane. If you are looking for a generator in this power output range I wholeheartedly recommend the Genmax generator.
